Description

  The present invention relates to a mounting structure of a ventilation building that is attached so as to cover an opening portion of a base plate of a single-flow roof that is inclined only on one side from above. In particular, the present invention relates to a roof material of a single-flow roof that is optimal for a roof material that is a metal roof and has a relatively low slope.

  Conventionally, a ventilation ridge is attached so that the opening part of the baseplate of the single-flow roof which inclines only to one side may be covered from upper direction.

  Such a ventilation building usually has an upper plate that is continuous with a vertical plate covering a vertical portion near the top of the single-flow roof, is inclined from the top portion to the eaves side along the inclined surface of the single-flow roof, and the upper plate. In general, it is composed of a lower plate disposed at a predetermined interval on the back side (lower side) of the base plate, and a passage between the upper plate and the lower plate communicating with the opening portion of the field plate is used as a ventilation path. (For example, see Patent Document 1).

JP 2001-303732 A

  The prior art described in Patent Document 1 does not consider attaching to a metal roof. In other words, when a metal roof is installed vertically, especially when the metal roof is installed in a vertical direction, rising parts that are convex at regular intervals are formed in the flow direction of the roof. Rainwater etc. will flow from the roof material surface other than.

  On the other hand, metal roofs are usually set so that the slope is low, and if the slope is low, the inflow of rainwater from the surface of the metal roof will increase compared to normal roofing materials, preventing such inflow of rainwater. There is a need.

  Therefore, there is a strong demand for the development of a ventilation ridge mounting structure that can be attached to a metal roof on which the rising portion is formed and can appropriately prevent rainwater from flowing into the metal roof surface.

To achieve this object, a single-flow roof ventilation building mounting structure according to the present invention has a ventilation path extending from the vicinity of the top of a single-flow roof of a building to the eaves side along the inclined surface of the roof, and a ventilation opening. The ridge is attached to a single-flow roof by a mounting base and a top support base.
By attaching a ventilation building having a ventilation path and a discharge port extending from the vicinity of the top of the single-flow roof of the building to the eaves side along the inclined surface of the single-flow roof to the single-flow roof, the ventilation building is stably converted into a single-flow roof, And it can be attached firmly. And even if it is a case where a ventilation building is arrange | positioned on the standup | rising part of a single flow roof, it can prevent that rainwater flows in from the eaves direction along roof materials other than a standup part.

  The top support is preferably mounted on a field plate near the top of the single-flow roof. In this case, the vicinity of the top of the ventilation building can be supported by the top support.

  It is preferable to attach a draining board bent in an inverted L shape across the butted portion of the mounting base and the roof material of the single-flow roof and a part of the upper surface of the roof material from the butted portion. In this case, it is possible to prevent rainwater from the eaves direction from flowing in from the abutting portion between the mounting base and the roof material of the single-flow roof.

  It is preferable to arrange a windproof rain plate outside the outlet on the eaves direction side of the ventilation building. In this case, rainwater can be prevented from flowing into the discharge port from the eaves direction of the ventilation building.

  The roofing material of the single-flow roof can be a metal roof. When the ventilation building is arranged on the rising part of the single-flow roof, rainwater tends to flow in from the eaves direction due to the presence of the rising part, and when the roof material of the single-flow roof is a metal roof, it is inclined. Since the angle is small and the slope is gentler, rainwater tends to flow in from the eaves direction. Therefore, in any case, it is necessary to prevent the inflow of rainwater from the eaves direction, but the inflow of the rainwater can be sufficiently prevented according to the ventilation building mounting structure for a single-flow roof according to the present invention.

  It is preferable to install a single flow building on both the left and right sides of the ventilation building. In this case, the left and right sides of the ventilation building can be covered with a single-flow building, so that not only ventilation through the ventilation building can be secured, but also the single-flow roof on the left and right sides of the ventilation building is protected from rainwater by both single-flow buildings. can do.

  It is preferable to cover the butt portion between the single-flow roof and the outer wall panel arranged so as to butt against the single-flow roof with the respective wing cover plates of the ventilation wing and the single-flow ridge. In such a case, rainwater does not enter the roof of the single-flow roof from the butt portion between the single-flow roof and the outer wall panel.

  According to invention of Claim 1, a ventilation building can be stably and firmly attached to a single flow roof. And even if it is a case where a ventilation building is arrange | positioned on the standup | rising part of a single flow roof, it can prevent rainwater flowing in from the eaves direction along roof materials other than a standup part.

  According to invention of Claim 2, since the top vicinity of a ventilation building can be supported by this top part support stand, there is no possibility that a ventilation building deform | transforms also in an area with much snow cover.

  According to invention of Claim 3, it can prevent that the rainwater from the eaves direction flows in from the butt | matching part of the mounting base and the roof material of a single flow roof.

  According to invention of Claim 4, it can prevent that rainwater flows in into a discharge port from the eaves direction of a ventilation building.

  According to the invention of claim 5, even if the ventilation ridge is arranged on the rising portion of the single-flow roof, and even if the roof material of the single-flow roof is a metal roof, from the eaves direction Inflow of rainwater can be sufficiently prevented.

  According to the sixth aspect of the present invention, not only can ventilation be ensured by the ventilation building, but also the single-flow roofs on both the left and right sides of the ventilation building can be protected from rainwater by the two single-flow buildings.

  According to invention of Claim 7, rainwater does not penetrate | invade into the attic of a single flow roof from the butt | matching part of a single flow roof and an outer wall panel.

It is an exploded perspective view of only the ventilation building of a single flow roof. It is a perspective view showing the state of construction of a ventilation tower with a single-flow roof. A mounting base and a top support base are attached to the top part of the field plate where the opening is formed, and roofing is performed across the lower surface on the flow side of the mounting base and the upper surface of the field plate After sticking a material, it is a perspective view which shows the state which attached the draining board while rolling up the metal roof which is a vertical flat roof material until it hits the flow lower surface of a mounting base. It is a perspective view which shows the mode of construction of the ventilation building of a single-flow roof, and is a perspective view which shows a mode that the ventilation building is fixed with a screw in alignment with the center of the opening of a field plate. It is a perspective view which shows the state which fixed the headboard according to the front opening part of the ventilation building on the mounting stand which is the both right and left sides of a ventilation building after an appropriate time. It is a perspective view which shows the state after the construction completion which covered the single flow building on the both right and left sides of a ventilation building from the state of FIG. 5, and was fixed with the screw.

An example of a single-flow roof ventilation building mounting structure according to the present invention will be described in detail with reference to the drawings. Here, an example is shown when the present invention is applied to a vertical roofing material in a single-flow roof that is inclined only on one side, in particular, when it is a metal roof, but it can also be used in the case of a tiled roof. it can.
As shown in FIGS. 1 and 3 to 6, the vertical metal roof is usually a roof that has a roofing method in which the roofing material 1 is started up in the flow direction of the single-flowing roof A in a way called “Yachiyo folding”. That is, the rising portions 1a and 1a are formed in the flow direction of the single-flow roof A at regular intervals.

  When such rising parts 1a and 1a are formed, rainwater and the like will flow from the surface of the roofing material 1 between the rising parts 1a and 1a simply by installing the ventilation tower B thereon. In order to prevent this intrusion in the single-flow roof A, in the present invention, the ventilation tower mounting structure of the single-flow roof A is devised.

The single-flow roof A usually has a field plate 2 that is inclined only on one side, and an opening 2a is formed in the field plate 2 near the top of the single-flow roof A, as shown in FIG. On the upper surface of the base plate 2 across the opening 2a, the mounting base 3 is positioned on the flow side of the opening 2a by a fixture such as a nail or a screw, and on the end surface of the top portion of the base plate 2. The top support 4 is fixed by aligning the right end surfaces of the top support 4 in FIGS. 1 and 3.
In addition, although the case where the mounting base 3 is attached so that the right end surface of the mounting base 3 in FIG. 1 coincides with the lower surface on the flow side of the opening 2a is illustrated here, the ventilation building B attached to the single-flow roof A As the gradient gradually increases, the mounting base 3 is attached to the top support base 4 gradually.

Thereafter, as shown in FIG. 3, the roofing material 5 is pasted over the lower surface of the mounting base 3 on the flow side and the upper surface of the base plate 2, and the metal roof that is the vertical flat roof material 1 is attached thereto. While rolling up until it hits the lower surface on the flow side of the table 3, a draining plate 6 bent in an inverted L shape is attached between them. Then, one surface of the draining plate 6 bent in an inverted L shape is inserted into the abutting portion between the lower surface on the flow side of the mounting base 3 and the metal roof that is the vertical roofing roof material 1. At the same time, the other surface of the draining plate 6 bent in an inverted L shape extends to the flow side of the single-flow roof A across the part of the upper surface of the roof material 1 from the butted portion.
Therefore, rainwater from the eaves direction can be prevented from flowing in from the abutting portion between the mount 3 and the roof material 1 of the single-flow roof A.

  Next, the ventilation ridge B is covered so as to cover the opening 2a from above the center of the opening 2a of the field board 2. As shown in detail in FIG. 2, the ventilation building B illustrated here has a lower plate 7 that can be placed and fixed on the mounting base 3, and an upper plate 8 that can substantially cover the lower plate 7. And a baffle plate 9 which is located between the upper and lower plates 8 and 7 and can keep a constant distance therebetween, as shown in FIG. They can be combined with each other on the upper side, and the screws 11 can be screwed and fixed from the mounting base 3 to the base plate 2 via the spacers 10. Thus, the ventilation building B composed of the lower plate 7, the upper plate 8 and the baffle plate 9 can be stably and firmly attached to the single-flow roof A.

The lower plate 7 follows the main body 7a placed on the mounting base 3, a guide plate 7b extending obliquely upward from the main body 7a in the direction opposite to the flow direction of the single-flow roof A, and the guide plate 7b. And a guide plate 7c extending in the flow direction of the single-flow roof A. Therefore, when the ventilation building B is fixed to the mounting base 3 as described above, the opening is formed in the passage c (FIG. 1) between the lower plate 7 and the upper plate 8 by the guide plate 7b and the guide plate 7c. Air from the portion 2a is induced.
Further, a storm plate 7d rising upward is formed at the edge of the main body 7a in the flow direction of the single-flow roof A.

  The upper plate 8 includes a main body 8a that widely covers the upper portion of the opening 2a of the base plate 2, and a ridge cover plate that extends downward from the edge of the main body 8a opposite to the flow direction of the single-flow roof A. 8b and a shielding plate 8c bent into a side L-shape from an end edge in the flow direction of the single-flow roof A of the main body 8a. A large number of exhaust ports 8d and 8d are formed in the shielding plate 8c with a constant interval in the width direction.

  On the other hand, the baffle plate 9 includes three contact plates 9a, 9b, and 9c that are alternately in contact with the back surface (lower surface) of the upper plate 8 and the upper surface of the lower plate 7, and between the contact plates 9a, 9b, and 9c. And two shielding plates 9d, 9e, and a shielding plate 9f extending downward from the edge in the flow direction of the single-flow roof A of the abutting plate 9c. The adjacent two partition plates 9d and 9e are formed with a large number of vents 9g and 9g at predetermined intervals in the width direction at positions alternately in the height direction.

  Therefore, even when the ventilation building B composed of the lower plate 7, the upper plate 8, and the baffle plate 9 is disposed on the rising portion of the single-flow roof A, the eave direction passes along the roof material other than the rising portion. Can prevent rainwater from flowing in. And the air induced | guided | derived to the said path | route c moves toward the flow direction of the single flow roof A through the said many vents 9g and 9g, and between the shielding board 9f of the said baffle board 9, and the said lower board 7 In addition, since it flows between the shielding plate 9f of the baffle plate 9 and the side L-shaped shielding plate 8c of the upper plate 8, it flows out from the multiple exhaust ports 8d, 8d to the outside of the single-flow roof A. The ventilation of the attic of the single-flow roof A can be performed reliably.

  On the other hand, since the storm plate 7d rising above the lower plate 7 is located outside the numerous exhaust ports 8d, 8d, the large number of exhaust ports from the eaves direction of the ventilation building B of the single-flow roof A. It is possible to prevent rainwater from flowing into 8d and 8d.

  In addition, the top part of the ventilation building B is supported by the top support base 4 attached on the base plate 2 near the top of the single-flow roof A. Therefore, there is no possibility that the ventilation building B is deformed even in an area with a large amount of snow.

  On the other hand, since the ridge cover plate 8b of the upper plate 8 covers the outside of the butt portion of the single-flow roof A and the outer wall panel D, rainwater may enter the attic of the single-flow roof A from the butt portion. Absent. And the lower end of the said ridge covering board 8b is bent inside, and it can prevent that rainwater permeates from between the outer wall panels D. The lower part of the ridge cover plate 8b is fixed to the outer wall panel D with screws 12.

  After covering the ventilation tower B so as to cover the opening 2a of the base plate 2, the headboards 13 and 13 are placed on the left and right sides of the ventilation tower B, and the exhaust on the front side of the ventilation tower B is shown in FIG. Fix according to the surface of the outlet 8d. And after applying a caulking agent to the left and right ends of the ventilation building B fixed to the single-flow roof A and applying a waterproof treatment, the left and right single-flow buildings E and E shown in FIG. Put on. At that time, as indicated by e ″ in the figure, the inner corners of the skirt portions e ′ of the two right and left single flow ridges E and E are cut out.

  Then, the left and right single flow buildings E, E arranged on both sides of the ventilation building B fixed to the single flow roof A are screwed (not shown) from the headboards 13, 13 as in the case of the ventilation building B. The top support 4 and the base plate 2 are screwed in and fixed, and also on the outer wall panel D side, the left and right single-flow ridges E, E ridge cover plates e, e are connected to the ridge cover plate in the ventilation ridge B. It fixes with a screw (illustration omitted) similarly to the case of 8b.

  Thus, the upper side of the opening 2a and the left and right sides of the single-flow roof A on which the roofing material 1 is stretched can be covered with the ventilation building B and the two right-and-left single flow buildings E and E. In this case, as described above, the ventilation of the attic of the single-flow roof A can be reliably performed. Moreover, not only can ventilation of the ventilation building B be ensured, but the single flow roofs A on both the left and right sides of the ventilation building B can be protected from rainwater by the two single flow buildings E and E. Further, on the side of the outer wall panel D, the wing covering plate 8b of the ventilation ridge B and the two right and left single-flow ridges E and the ridge-covering plates e and e of E are arranged. Rainwater does not enter the attic of the single-flow roof A from the butt portion.

  As shown in FIGS. 3 to 6, a plurality of rafters 14 and 14 are arranged on the lower surface of the base plate 2 of the single-flow roof A along the flow direction of the single-flow roof A with a certain interval.

Here, taking as an example the case where the rising portion 1a is formed on the roofing material 1 stretched around the single-flow roof A, an example of the ventilation building mounting structure of the present invention has been described. The ventilation building mounting structure of the present invention can also be applied to a single-flow roof that is a metal roof that is not formed and is usually set to have a low slope.
